In its original conception, the .rtf format was a specification for formatting text and graphics principally designed to facilitate the interoperability of documents and text between Microsoft document processing applications. It eliminated the need for specialized translation software required to open documents in different versions of MS-DOS, Windows, and Macintosh. The specification is a proprietary filename format first developed by Microsoft in 1987 to be supported in Microsoft word 3.0 and all versions of Microsoft Office Word thereof. The latest revision, version 1.9.1, was released in 2008 and also marked the end of any further enhancements to the specification by Microsoft. Through unformatted text, control words, control symbols, and groups, a piece of text can be encoded into an .rtf format. All RTF readers then process .rtf formats by separating and acting on control information disparately from the actual text in the document. Though the RTF specification is proprietary asset of Microsoft, several non-Microsoft programs support both reading .rtf documents and creating .rtf. Microsoft Office Suite is still however the most dominant application associated with this specification.
The .mobi filename extension is an eBook file format developed by French company MobiPocket for their ebook readers for mobile phones and PDAs. The company was later acquired by book reseller and online store company Amazon in 2005, a deal which included the mobi format asset. The mobi file format is mostly associated with the mobipocket software package as well as early versions of Amazon's kindle ebook reader device. The format is considered cross platform given its compatibility with several devices including most smartphones that have compatible readers installed. But although mobi files still exist in circulation, the format was superseded by Amazon's AZW format when support and further development of mobi ceased in 2011.

Extended ASCII, PC-8, and ANSI are among the original character control sets used in the formatting and text representation of documents saved in the .rtf format. At present the format supports 7-bit ASCII characters. This formally allows the easy transfer of text documents between different computers running different operating systems and applications. RTF requires minimal computer resources and does not support macros. It does however have support for embedding some of the popular graphical format such as JPEG and PNG. Not all applications have support for these embedded graphical format thus .rtf files with unsupported embedded graphical images will open but will not display the graphical images.
The mobi file format extends the popular HTML specification adding DRM protection support. It includes advanced file navigation support such as indexing, book marks, notes, and annotations. The format is adapted to reflowing content layout to optimally use the screen size of its device, but it has a hard limitation of 64 kilobytes for images which may cause image files to incorrectly display on larger displays such as tablets and pc monitors.
